Technical field
The utility model belongs to the fuel gas alarm detection field, is specifically related to a kind of fuel gas alarm detecting unit.
Background technology
At present, the common supporting installation fuel gas alarm of household gas utensils.The occasion of the higher inflammable and explosive risk that is applicable to all kinds of Gas appliances and brings (such as family kitchen, use the toilet of gas heater etc.), in surrounding air, there are coal gas or concentration of natural gas to arrive warning concentration, alarm can send sound and light alarm, and output signal drives solenoid valve shutoff coal gas or rock gas.
For the factory testing of alarm output signal, most of producers are with the fuel gas alarm connected electromagnetic valve, and the manual triggers alarm is by its output of reporting to the police, and whether the manual observation solenoid valve moves.If solenoid valve is failure to actuate, illustrate that output signal has problem.This detection method is just higher to the artificial dependence in scene, error occurs easily.When manufacturer when dispatching from the factory the product mass detection, this method troublesome poeration, efficient is low.Examine and determine fast in the urgent need to a kind of modern detection means.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of fuel gas alarm detecting unit, be applied in the fuel gas alarm pick-up unit, described pick-up unit is by the output data of fuel gas alarm under specific environment, duty to fuel gas alarm is judged, realizes fuel gas alarm is detected calibrating.
Fuel gas alarm detecting unit described in the utility model is equally applicable to quality testing and the calibrating of the combustible gas probe product of similarity.
Its technical scheme is:
The Household gas warner detecting unit is applied in the Household gas warner pick-up unit.The Household gas warner pick-up unit comprises the calibrating gas test box, gas tester, brassboard, alarm detecting unit; Brassboard is arranged in the calibrating gas test box; Place the fuel gas alarm that pre-calibrating detects on the brassboard, and be electrically connected with the alarm detecting unit;
The alarm detecting unit connects gas tester, and the detection probe of gas tester contacts with gas in the calibrating gas test box;
Calibrating gas test box good seal, the inside gassy during detection; Be provided with air intake opening in the tank wall, exhausr port.Air intake opening connects external air source by gas piping, the air inlet electromagnetic valve of connecting on the gas piping.Same, exhausr port also connects outside by gas piping, the solenoid valve of giving vent to anger of connecting on the gas piping; Air inlet electromagnetic valve is connected with the alarm detecting unit respectively with the solenoid valve of being connected.
The Household gas warner detecting unit is take microprocessor as core circuit; The output terminal electrical connection of microprocessor and alarm signal acquisition circuit, the input end of alarm signal acquisition circuit connects the output terminal of fuel gas alarm to be measured; Microprocessor connects the Control terminal simultaneously, and connects computing machine by the microprocessor communication interface; Relay be used for the resetting fuel gas alarm of pre-detection,
The fuel gas alarm that the electrical connection of alarm signal acquisition circuit is to be measured and the output terminal of gas tester; The alarm signal acquisition circuit adopts multi-channel A/D circuit, can carry out simultaneously multiplexed signal sampling;
The alarm detecting unit is connected with computer system, makes the output signal of alarm detecting unit by Computer display, and carries out communication and transmission of information by computing machine and alarm detecting unit.
Use the communication of RS232 agreement between alarm detecting unit and the computer system;
Another kind of communication modes is wireless contact between alarm detecting unit and the computer system, and alarm detecting unit and computing machine carry out wireless connections by wireless communication module; So just realized the remote detection of fuel gas alarm;
Beneficial effect:
But use the alarm detecting unit of multiplexed signal sampling, realized that the alert device of many newspapers combustion gas can detect calibrating simultaneously, has greatly improved detection efficiency, and has realized automatic technology; The long distance wireless detection technique just can be checked testing result so that managerial personnel needn't be in the action, and in time carries out feedback management.Promote the technical management level, improved duty.
Adopt the disclosed alarm detecting unit of the utility model, manufacturer provides accuracy and the check speed of the examination and test of products when dispatching from the factory the product mass detection, reduces manually participating in, and has realized modernized quality inspection method.
